But that is, however, not at all what I am saying, and certainly not what I wish to suggest either!! I have no doubt that you are trained on dealing with intoxicated passengers (in fact I didn't even know that you do not have a specific module on it). I was referring specifically to training on identifying pre-intoxication signs. In other words learning (from medical practitioners) the specific signs of impending intoxication of someone who does not look drunk at all. Some other airlines that I know of train crew about this specific, technical issue and I do not believe that BA does regardless of what other training the airline may provide on dealing with drunken passengers which is of course useful as well but different.
